The gender wage gap within a highly prestigious occupation, the medical profession, is investigated both longitudinally and cross-sectionally using Swedish administrative data. This is done by investigating: to what extent the gender wage gap among physicians varies between fields of medicine (within-occupation segregation) and across family status; whether there is an association between parenthood and wages among physicians and, if so, whether there is a gender difference in this association; and changes in the gender wage gap among physicians over time. The results indicate a large overall gender wage difference for medical doctors. Even when gender differences in specialization are taken into account, men have higher wages than women do. For both men and women physicians, there is a positive association between parenthood and wages. The longitudinal analyses show that the gender wage gap among physicians was greater in 2007 than in 1975.
